E.T.
We just got our pool installed the end of April. So far the water bill has only been $2-5/month more than last year's (minus the month where we had it filled). We add a little bit of water every week since it evaporates from the heat. And we do it while we're swimming so that it cools the pool down a little! Electric has stayed the same (we paid a little more for a better variable speed pump). Part of the reason though too is that we are very diligent about turning our A/C up when we are outside in the pool (and make sure the lights/tv are off too). After you come inside from swimming, you're really cooled off and don't need that much A/C. We have a salt pool and it's been a very minimal expense in regards to chemicals. Our insurance only went up $20 a year for coverage. It really only takes us 30 mins - 1 hr a week to brush the pool, check the chemicals and clean the filters. We do it all ourselves usually when the kids are swimming (and I brush the pool while I'm in the water). The pool is VERY MUCH worth it!! We're in it all of the time. I absolutely think it's a GREAT investment - especially if you have kids. Everyone wants to come over to our house which will really pay off when the kiddos are older so that I can keep an eye on what they're doing! HTH!
